Muffler for staple guns

Abstract

A muffler is received in a passage of an end member connected to a handle of the staple gun and a fitting extends from the end member so as to be connected to a hose. The muffler includes a tubular body and a plurality of plates extend from an end of the tubular body. The plats extend toward an interior of the handle and form a bullet-head-shaped arrangement. Gaps are defined between the plates and become smaller when air goes outward from the handle so as to reduce noise.

1. A noise reducing device for a staple gun which comprises a body with a nose connected to a front end thereof and a trigger pivotably connected to a handle of the staple gun, the device comprising:
 an end member adapted to be connected to the handle and having a fitting extending therefrom, a passage defined through the end member and communicating with the fitting, and 
 a muffler comprising a tubular body which is received in the passage of the end member and a plurality of plates extending from an end of the tubular body, the plates adapted to extend toward an interior of the handle, gaps defined between the plates, and the gaps between the plates are smaller when air exits end member. 
 
   
   
     2. The device as claimed in  claim 1 , wherein the plates are located side by side so as to form a domed shaped arrangement. 
   
   
     3. The device as claimed in  claim 2 , wherein a hole is defined in a center encompassed by respective tips of the plates. 
   
   
     4. The device as claimed in  claim 1 , wherein the passage of the end member includes a threaded inner periphery and the tubular body of the muffler includes a threaded outer periphery which is engaged with the threaded inner periphery of the end member.
